Hibiscus plant named ‘Belize Breeze’

ABSTRACT

A new and distinct  Hibiscus  plant named ‘Belize Breeze’, characterized by its compact, upright, outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production; glossy and dark green-colored leaves; uniform and freely flowering habit; pink-colored flowers with white centers; good resistance to flower bud abscission during shipping; and tolerance to pathogens common to  Hibiscus  grown under Florida production conditions.

Botanical designation: Hibiscus rosa-sinensis.

Cultivar denomination: ‘Belize Breeze’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the name ‘Belize Breeze’.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Alva, Fla. The objective of the breeding program is to create new freely-branching Hibiscus cultivars with a dense, uniform and compact plant habit appropriate for container production, early and uniform flowering, numerous flowers per lateral branch, desirable flower color and good postproduction longevity.

The new Hibiscus originated from a cross-pollination made by the Inventor in Alva, Fla. in late 1998, of a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1390, not patented, as the female, or seed, parent with the Hibiscus rosa-sinensis cultivar Kardinal Pink, not patented, as the male, or pollen, parent. The cultivar Belize Breeze was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., on Sep. 27, 2000.

Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Alva, Fla. since February, 2001, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Belize Breeze has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Belize Breeze’. These characteristics in combination distinguish ‘Belize Breeze’ as a new and distinct cultivar:

-   -   1. Upright, outwardly spreading, uniform, dense and symmetrical         plant habit that is appropriate for container production.     -   2. Glossy, palmately-lobed and dark green-colored leaves.     -   3. Uniform and freely flowering habit.     -   4. Ruffled pink-colored flowers with white centers.     -   5. Good resistance to flower bud abscission during shipping.     -   6. Tolerant to pathogens common to Hibiscus grown under Florida         production conditions.

Plants of the new Hibiscus can be compared to plants of the female parent, the proprietary Hibiscus selection code number YB-1390. Plants of the new Hibiscus differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Hibiscus are not as vigorous as plants of         the female parent selection.     -   2. Plants of the new Hibiscus have palmately-lobed foliage         whereas plants of the female parent selection do not have lobed         foliage.     -   3. Plants of the new Hibiscus and the female parent selection         differ in flower color as plants of the female parent selection         have lighter pink-colored flowers and pink centers.

Plants of the new Hibiscus can be compared to plants of the male parent, the cultivar Kardinal Pink. Plants of the new Hibiscus differ from plants of the cultivar Kardinal Pink in the following characteristics:

-   -   1. Plants of the new Hibiscus are not as vigorous as plants of         the cultivar Kardinal Pink.     -   2. Plants of the new Hibiscus and the cultivar Kardinal Pink         differ in flower color as plants of the cultivar Kardinal Pink         have lighter pink-colored flowers with dark pink centers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar Pink Versicolor, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of the cultivar Pink Versicolor in the following characteristics:

-   -   1. Plants of the new Hibiscus were more freely flowering than         plants of the cultivar Pink Versicolor.     -   2. Plants of the new Hibiscus and the cultivar Pink Versicolor         different in flower color as plants of the cultivar Pink         Versicolor had dark rose pink-colored flowers with dark pink         centers.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Alva, Fla., with five plants per 16.5-cm container in polyethylene-covered greenhouses during the late summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 16 to 37° C. and night temperatures ranged from 13 to 26° C. Plants were about four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
